This would seem to prevent the firestorm from spreading on the wind, but for the fact that tremendous turbulence is also created by the strong updraft which causes the strong surface inflow winds to change direction erratically.

These little droplets are especially light and so it is easier for them to rise to higher levels of the cloud on thermal updrafts.

Wouldn't that spell for a non-optimist more massive updrafts, change the ionization progression of O2 and other upper atmosphere components, distort the terrestrial solar tide and create shearing effects that contribute to turbulence and Bernoulli effects?

While we can expect that PV will likely be cheaper in the future, solar updraft towers could provide an economically - viable alternative to «PV + energy storage» for peak load (as solar updraft towers can store thermal energy in the ground for night electricity production to greatly reduce intermittency at minimal additional cost).

For convection, we could separate the amount of energy transfered vertically into updrafts and downdrafts.

Re 68 (myself)-- of course, some tornados are not from supercells — or are not formed by the exact same mechanism; generally what is needed is an updraft over a region of partly horizontal shear such as that associated with a gust front — it could be a gust front from another storm... there are landspouts, gustnados, etc... these tend to be weaker then the supercell tornados, as far as I know (And I'm not entirely sure what defines a «landspout»; for that matter, if a supercell tornado moves over water, is it then a waterspout or is it still a supercell tornado... anyone?)
